VTOL tilt bi-rotor (OV-22 osprey like)

Hi there. I’m brand new into PX4 and Pixhawk’s world.
I’m building a tilt bi-rotor (it looks like an OV-22) but I wasn’t able to find how to configure it with PX4.
What I saw as defined setups, this kind of VTOL is not listed.
Do you have any idea how to proceed ?

To illustrate what I want to do.

I’m no expert but maybe try the EFlite Convergence airframe then disable the rear motor?

Good luck.

I think it will be more a mix convergence and standard_plane as there are ailerons and elevator not only elevons (rudder is not mendatory at first time).
